Due to its antiquity, there exist various foundation myths for Nowruz in Iranian mythology. In the Zoroastrian tradition, the seven most important Zoroastrian festivals are the six Gahambars and Nowruz which occurs at the spring equinox. According to the late Professor Mary Boyce: It seems a reasonable surmise that Nowruz, the holiest of them all, with deep doctrinal significance, was founded by Zoroaster himself. Between sunset of the day of the 6th Gahanbar and sunrise of Nowruz was celebrated Hamaspathmaedaya (later known, in its extended form, as Frawardinegan). This and the Gahanbar are the only festivals named in the surviving text of the Avesta.
